What is the Signature Select Hydration Amplifier?

The Hydration Amplifier addresses dry, dehydrated skin.  It helps support the skin microbiome by repairing and protecting the skin’s moisture barrier and infusing the skin with hydration.  The hydration amplifier can be used alone in the base serum or with up to two other amplifiers such as Brightening and Anti-Wrinkle.  If using with other amplifiers, insert the Hydration Amplifier first.
